Moose Offroad Choke Plunger Rebuild Kit – Yamaha Grizzly / Big Bear / Wolverine / Bruin / Raptor / Kodiak (2000–2014) – OEM‑Spec Components, Reliable Fuel Control

OVERVIEW

The Moose Racing 1003-1786 Choke Plunger Rebuild Kit restores proper fuel-air balance and cold-start capability by replacing seized or lost internal mechanisms within carburetor assemblies. Manufactured with durable rubber O-rings, hardened steel springs, and precision retainers, this carburetor part supplies essential components for reliable engine operation. Engineered exclusively for vintage and legacy Yamaha utility and sport ATV platforms.

ENGINEERING & PERFORMANCE

Carburetor choke plungers frequently seize due to varnish accumulation or go missing during routine maintenance, leading to poor idle quality and unreliable ignition. This kit rebuilds the complete assembly to maintain consistent airflow and fuel delivery during warm-up cycles. Constructed with corrosion-resistant metal retainers and flexible rubber seals, it resists degradation from fuel additives and engine heat. Engineered for direct OEM-style fitment, it restores precise linkage action for both single and multi-carbureted models without modification.
